title4 November 2023

Modules

  • Added inserts to the remaining top cell holders + top covers

  • Potted busbars for another cell holder, but ran out of busbars for more (waiting on the dwg file so we can cut another batch)

  • Measured cell voltages for another module's worth of cells

  • @Nicole Choe and @Taylor Elena Avery Hazelwood worked on enclosure jig manufacturing

  • @jenna k was working on CAD for aux. finished except securing mechanism needed to baffle, probs bolted connection

Enclosure:

  • Progress made on manufacturing modules. Manufacturing modules, but ran out of busbars - Vaibhav to message Caleb, who was in charge for water-jet files to forward the file to the group

  • Steel Flat Jig was tested and fits to chassis. Taylor cut 3/4 wood pieces needed for our enclosure jig, and I've asked her to cut holes for two of them. To be completed by Saturday

  • All screws set aside for Enclosure jig.

  • Tested another 32 cells for the module

  • Welding deadline for steel flat to enclosure is November 15th. Waiting for angle irons (hopefully in by wed 8th)

  • Enclosure panel MDF cutting needs to be redone - to be completed by Wednesday's working session (November 8th)

  • As soon as the angles arrive - Jenna to send a message @channel so machining can start as soon as possible.

  • 3D Prints to be assigned by Shem, after his Enclosure Design meeting with Jenna

title9 Nov November 2023

  • Finished milling steel flats, cut to-size +- 0.4mm (outside XV-BAT129 Steel_Cross_Bar cut -0.9mm). This issue will be fixed by welding. Disregard yesterday's 2mm undersize, that was a mistake

  • Finished cutting angle irons - will be milled to-size by tomorrow 

  • Worked with Machine Shop Guy to plan cutting holes into parts using mill - will finish tomorrow

  • Validating Chassis Cross bar jig tomorrow by milling holes into a scrap 1/4" piece

  • 1/4" Steel for Chassis Cross bar has not arrived yet. Will ping when metal arrives

  • MDF for the enclosure jig is all cut! Thank you so much @jenna k

HUGE SHOUT-OUT TO @Jericho Mordasiewicz @Taylor Elena Avery Hazelwood @Jason Siu @Evan McMahon for all your help today and for coming in tomorrow to finishing up the milling, you guys are awesome : ))) I will ping you guys to tomorrow's instructions in this channel in a thread (edited) 

Thursday Manufacturing Instructions - Milling Holes @Evan McMahon @Jason Siu

title11 November 2023

  • Michael has said resin for panel should be coming in next week (stated Nov 12)

Aux Battery

  • Cells have been tested, working this week to group cells and spotweld this week

Module Testing

  • Initial discharge test conducted, nothing on fire

  • Will work to get the code right for the daq to collect data for future tests for production modules

Module Manufacturing

  • Single and voltage taps completed

  • Voltage checked for cells for 12 modules

Enclosure

  • Chassis jig is within tolerance

  • Milled holes into Steel Flats and all but one angle iron

  • Assembled a portion of the enclosure jig

  • One of the MDF pieces needs to be re-cut. Vaibhav will create the drawing and get it done by Monday

  • Added another connector for solar relay to the enclosure cad. No more changes exist for the enclosure design. Left the connectors in our prototype box in the bay.

  • CAD a cap for impounding for the new connector added (required by regs). He finished the CAD so I will review tmrw, but it’s relatively simple so I don’t imagine there should be any problems.

  • Made confluence page for all electrical components inside enclosure. Enclosure Electrical Components & Harnessing
